Our reference materials
NMI certified reference materials
Our certified reference materials have established metrological traceability to the SI unit for mass (kg). We report all purity values, stated as a mass fraction, with the associated uncertainty in the certificate of analysis.
Our reference materials have demonstrated homogeneity and stability.
We have NATA accreditation for producing matrix reference materials and assigning reference values under:
- ISO 17034:2016 General requirements for the competence of reference material producers.
- ISO/IEC 17025:2017 General requirements for the competence of testing and calibration laboratories.
